Abstract: Ubiquitous Healthcare is essential not only for providing efficient medical care but also in saving medical expenses. Currently, sensor networks are widely used for applications such as environmental monitoring, airport safety, healthcare, etc. In healthcare situations, sensor nodes can be deployed to remotely monitor and assist disabled patients. Also a concern is the protection of privacy with electronic communication of patient data. However, the sensor networks are easily compromised if an attacker sends forged or modified messages. If a medical unit receives false messages and all efforts of the working staff are implemented under false pretenses, the loss of resources and manpower would be great. Therefore, the receiver (medical unit) has to authenticate messages transmitted from the sensor nodes (monitored patients) over the wireless sensor network. To provide the quality and security of the growing healthcare, it is necessary to reduce the computation load for both parties of the medical unit and the monitored patient. In this study, we will present a new security and privacy of authentication so that ubiquitous healthcare is possible through the sensor network.
